DESCRIPTION OF EXAMPLE EMBODIMENTS

Client devices may communicate one or more video streams to a computer server machine. The video streams may be associated with a video session, and each client device may respectively be associated with a user. The computer server machine, in turn, may communicate the one or more video streams associated with a video session to one or more client devices.

This approach may be limited and inefficient. For example, a user associated with the client device receiving the one or more video streams associated with the video session may either be required to view each of the one or more video streams to identify an interest moment. Moreover, a user associated with the client device receiving the one or more video streams may overlook an interesting moment associated with one or more video streams.

Accordingly, particular embodiments provide techniques to identify and record interesting events by individuals in a video session. A computer server machine receives, from one or more client devices, one or more video streams associated with a video session associated with one or more users. The one or more users are respectively associated with each client device. The computer server machine analyzes the one or more video streams to identify an interesting event and generates a marker for the one or more video streams based on a time associated with the identified interesting event. The computer server machine sends information regarding the marker to the one or more client devices.

In addition, in a real-time group chatroom, a computer server machine may receive one or more video streams from one or more client devices with each client device respective associated with a user. The computer server machine, in turn, may communicate the one or more video streams to one or more client devices. Moreover, when no participants are active in the group chatroom, the group chatroom may cease to exist.

This approach may also be limited and inefficient. For example, a persistent real-time group chatroom may continue to be active even when zero participants are active. In addition, a non-active participant that is not active in the persistent real-time group chatroom may receive a notification if one or more participants become active (e.g., communicating a video stream) in the group chatroom.

Accordingly, particular embodiments provide techniques to provide a persistent real-time group chatroom that notifies non-active participants of activity in the group chatroom. A computer server machine maintains a persistent real-time group chatroom comprising one or more participants. At any given time, zero or more participants are active in the group chatroom. The computer server machine receives one or more video streams associated with a video session associated with one or more users. The video streams are communicated from one or more client devices with each client device respectively associated with the one or more users. The computer server machine provides a notification to one or more non-active participants, wherein the one or more non-active participants are not active in the persistent real-time group chatroom.

Herein, reference to a webpage encompasses one or more corresponding webpage files (which a browser may use to render the webpage) and vice versa, where appropriate.

In particular embodiments, social-networking system 160 may be a network-addressable computing system that can host an online social network. Social-networking system 160 may generate, store, receive, and send social-networking data, such as, for example, user-profile data, concept-profile data, social-graph information, or other suitable data related to the online social network. Social-networking system 160 may be accessed by the other components of network environment 100 either directly or via network 110. As an example and not by way of limitation, client system 130 may access social-networking system 160 using a web browser 132, or a native application associated with social-networking system 160 (e.g., a mobile social-networking application, a messaging application, another suitable application, or any combination thereof) either directly or via network 110. In particular embodiments, social-networking system 160 may include one or more servers 162. Each server 162 may be a unitary server or a distributed server spanning multiple computers or multiple datacenters. Servers 162 may be of various types, such as, for example and without limitation, web server, news server, mail server, message server, advertising server, file server, application server, exchange server, database server, proxy server, another server suitable for performing functions or processes described herein, or any combination thereof. In particular embodiments, each server 162 may include hardware, software, or embedded logic components or a combination of two or more such components for carrying out the appropriate functionalities implemented or supported by server 162. In particular embodiments, social-networking system 160 may include one or more data stores 164. Data stores 164 may be used to store various types of information. In particular embodiments, the information stored in data stores 164 may be organized according to specific data structures. In particular embodiments, each data store 164 may be a relational, columnar, correlation, or other suitable database. Although this disclosure describes or illustrates particular types of databases, this disclosure contemplates any suitable types of databases. Particular embodiments may provide interfaces that enable a client system 130, a social-networking system 160, or a third-party system 170 to manage, retrieve, modify, add, or delete, the information stored in data store 164.

In particular embodiments, social-networking system 160 may store one or more social graphs in one or more data stores 164. In particular embodiments, a social graph may include multiple nodes—which may include multiple user nodes (each corresponding to a particular user) or multiple concept nodes (each corresponding to a particular concept)—and multiple edges connecting the nodes. Social-networking system 160 may provide users of the online social network the ability to communicate and interact with other users. In particular embodiments, users may join the online social network via social-networking system 160 and then add connections (e.g., relationships) to a number of other users of social-networking system 160 to whom they want to be connected. Herein, the term “friend” may refer to any other user of social-networking system 160 with whom a user has formed a connection, association, or relationship via social-networking system 160.

In particular embodiments, social-networking system 160 may provide users with the ability to take actions on various types of items or objects, supported by social-networking system 160. As an example and not by way of limitation, the items and objects may include groups or social networks to which users of social-networking system 160 may belong, events or calendar entries in which a user might be interested, computer-based applications that a user may use, transactions that allow users to buy or sell items via the service, interactions with advertisements that a user may perform, or other suitable items or objects. A user may interact with anything that is capable of being represented in social-networking system 160 or by an external system of third-party system 170, which is separate from social-networking system 160 and coupled to social-networking system 160 via a network 110.

In particular embodiments, social-networking system 160 may be capable of linking a variety of entities. As an example and not by way of limitation, social-networking system 160 may enable users to interact with each other as well as receive content from third-party systems 170 or other entities, or to allow users to interact with these entities through an application programming interfaces (API) or other communication channels.

In particular embodiments, a third-party system 170 may include one or more types of servers, one or more data stores, one or more interfaces, including but not limited to APIs, one or more web services, one or more content sources, one or more networks, or any other suitable components, e.g., that servers may communicate with. A third-party system 170 may be operated by a different entity from an entity operating social-networking system 160. In particular embodiments, however, social-networking system 160 and third-party systems 170 may operate in conjunction with each other to provide social-networking services to users of social-networking system 160 or third-party systems 170. In this sense, social-networking system 160 may provide a platform, or backbone, which other systems, such as third-party systems 170, may use to provide social-networking services and functionality to users across the Internet.

In particular embodiments, a third-party system 170 may include a third-party content object provider. A third-party content object provider may include one or more sources of content objects, which may be communicated to a client system 130. As an example and not by way of limitation, content objects may include information regarding things or activities of interest to the user, such as, for example, movie show times, movie reviews, restaurant reviews, restaurant menus, product information and reviews, or other suitable information. As another example and not by way of limitation, content objects may include incentive content objects, such as coupons, discount tickets, gift certificates, or other suitable incentive objects.

In particular embodiments, social-networking system 160 also includes user-generated content objects, which may enhance a user's interactions with social-networking system 160. User-generated content may include anything a user can add, upload, send, or “post” to social-networking system 160. As an example and not by way of limitation, a user communicates posts to social-networking system 160 from a client system 130. Posts may include data such as status updates or other textual data, location information, photos, videos, links, music or other similar data or media. Content may also be added to social-networking system 160 by a third-party through a “communication channel,” such as a newsfeed or stream.

In particular embodiments, social-networking system 160 may include a variety of servers, sub-systems, programs, modules, logs, and data stores. In particular embodiments, social-networking system 160 may include one or more of the following: a web server, action logger, API-request server, relevance-and-ranking engine, content-object classifier, notification controller, action log, third-party-content-object-exposure log, inference module, authorization/privacy server, search module, advertisement-targeting module, user-interface module, user-profile store, connection store, third-party content store, or location store. Social-networking system 160 may also include suitable components such as network interfaces, security mechanisms, load balancers, failover servers, management-and-network-operations consoles, other suitable components, or any suitable combination thereof. In particular embodiments, social-networking system 160 may include one or more user-profile stores for storing user profiles. A user profile may include, for example, biographic information, demographic information, behavioral information, social information, or other types of descriptive information, such as work experience, educational history, hobbies or preferences, interests, affinities, or location. Interest information may include interests related to one or more categories. Categories may be general or specific. As an example and not by way of limitation, if a user “likes” an article about a brand of shoes the category may be the brand, or the general category of “shoes” or “clothing.” A connection store may be used for storing connection information about users. The connection information may indicate users who have similar or common work experience, group memberships, hobbies, educational history, or are in any way related or share common attributes. The connection information may also include user-defined connections between different users and content (both internal and external). A web server may be used for linking social-networking system 160 to one or more client systems 130 or one or more third-party system 170 via network 110. The web server may include a mail server or other messaging functionality for receiving and routing messages between social-networking system 160 and one or more client systems 130. An API-request server may allow a third-party system 170 to access information from social-networking system 160 by calling one or more APIs. An action logger may be used to receive communications from a web server about a user's actions on or off social-networking system 160. In conjunction with the action log, a third-party-content-object log may be maintained of user exposures to third-party-content objects. A notification controller may provide information regarding content objects to a client system 130. Information may be pushed to a client system 130 as notifications, or information may be pulled from client system 130 responsive to a request received from client system 130. Authorization servers may be used to enforce one or more privacy settings of the users of social-networking system 160. A privacy setting of a user determines how particular information associated with a user can be shared. The authorization server may allow users to opt in to or opt out of having their actions logged by social-networking system 160 or shared with other systems (e.g., third-party system 170), such as, for example, by setting appropriate privacy settings. Third-party-content-object stores may be used to store content objects received from third parties, such as a third-party system 170. Location stores may be used for storing location information received from client systems 130 associated with users. Advertisement-pricing modules may combine social information, the current time, location information, or other suitable information to provide relevant advertisements, in the form of notifications, to a user.

In certain embodiments, server 162 comprises a computer server machine. Computer server machine may be any component in social-networking system 160 and can communicate with any component inside social-networking system 160. However, although computer server machine is described herein as server 162, computer server machine may be any component that exists independent of social-networking system 160. For example, computer server machine may be a standalone module that is external to social-networking system 160. In particular embodiments, computer server machine may communicate with third-party system 170 and client system 130.

In certain embodiments, client system 130 comprises a client device. Client device may be any component in social-networking system 160 and can communicate with any component inside social-networking system 160. However, although client device is described herein as client system 130, client device may be any component that exists independent of social-networking system 160. For example, client device may be a standalone module that is external to social-networking system 160. In particular embodiments, client device may communicate with server 162 and third-party system 170.

In an exemplary embodiment of operation, server 162 receives one or more video streams from one or more client systems 130. Video streams may be a form of multimedia that is transmitted over the Internet in near real time. Rather than wait for the entire video to arrive, server 162 may continuously receive and capture the received video stream. Client system 130 may capture a video stream by using a video camera, microphone, speaker, or any other mechanism to record video and/or audio. In certain embodiments, a video stream may comprise a video component, an audio component, or both a video and audio component. Client system 130 may transmit a video stream to server 162. In certain embodiments, multiple client systems 130 may each respectively transmit a video stream to server 162.

Moreover, the video streams may be associated with a video session. A video session comprises at least one video stream. A video session may comprise video streams from one or more video streams associated with one or more users wherein the one or more users are communicating with one another. In certain embodiments, a video session contains one or more active speakers and one or more active listeners. Server 162 may utilize a video session to determine how to display the one or more video streams associated with the video session to client systems 130. In certain embodiments, server 162 identifies the one or more active speakers and/or one or more active listeners. Server 162 may then communicate the one or more active speakers to client systems 130. In this embodiment, server 162 may still continue to capture and process the one or more active listeners. Moreover, server 162 may communicate the video component of a subset of one or more video streams and also communicate the audio component of each one or more video streams.

In certain embodiments, server 162 stores the received one or more video streams. Server 162 may store the entirety of the received video streams, or may store a predefined and/or adaptive segment of the received video stream. For example, server 162 may automatically store the previous ten minutes of the received one or more video streams. In certain embodiments, server 162 accesses a privacy server associated with the user of the one or more video streams to determine whether the privacy settings allow server 162 to store the received video streams. For example, certain European countries have strict image rights such that storing a video stream of a person may be unlawful without the express consent of the user. In these embodiments, server 162 will only store a video stream of the user if the user provides consent for server 162 to store the video. The user may provide consent for server 162 to store the video in the user's privacy settings stored on the privacy server.

Server 162 may analyze the one or more received video streams to identify an interesting event. An interesting event may be any type of noteworthy event that occurs in a video stream. For example, a sudden shriek in a video may be an interesting event in certain embodiments. Server 162 may analyze the one or more received video streams proactively as client system 130 communicates a video stream to server 162 and/or server 162 may analyze the video streams retroactively. The following paragraphs discuss exemplary methods for analyzing the one or more video streams to identify an interesting event.

In certain embodiments, server 162 may associate one or more actions associated with a video stream as an interesting event. For example, if a video stream receives several “like” actions during a time period, server 162 may flag that moment as an interesting moment. Server 162 may have a preset threshold for when to tag a video as interesting (e.g., a certain number of comments associated with the video stream) or the threshold may be adaptive. Actions, moreover, may constitute comments, likes, or any other type of user action that is associated with the one or more video streams.

Server 162 may also detect a change in audio content and determine the change in audio warrants marking as an interesting moment. As an example, a person may raise his or her voice on the audio stream. Server 162 may determine that the changing volume of the voice constitutes a change in audio and may mark that as an interesting moment. Server 162 may analyze the audio spectrum of the audio stream to determine if a change in the audio is significant to warrant labeling as an interesting moment.

In certain embodiments, server 162 detects a change in an attribute of the video stream, and record that change as an interesting moment. An attribute of the video stream may be one or more characteristics of the video and/or audio component of the video stream. For example, an attribute of the video stream may include quality of the video stream, lag of the video stream, amount of data used to stream video stream, users watching the video stream (including number of active viewers of the video stream), connection quality, audio and/or video format, frame rate, aspect ratio, bits per pixel, video compression method, or any other characteristic associated with the video stream.

Server 162 may also use facial recognition computer software to identify an emotion associated with a user of client system 130. In certain embodiments, server 162 may identify an interesting moment based on the emotion associated with the user of client system 130. For example, server 162 may automatically identify an interesting event when the user of client system 130 displays an emotion of surprise. Moreover, server 162 may identify a change in emotion as an interesting event.

Server 162 may also apply analysis on the environment captured in a video session of client system 130. Server 162 may detect a change in the environment (e.g., a cat walking across the room), may detect an unusual pattern in the environment (e.g., a shooting star), or may perform any other type of analysis such that server 162 can detect an interesting moment in the received one or more video stream.

In particular embodiments, server 162 may customize the detection of an interesting moment based on information related to the user profile associated with client device 130. Server 162 may customize the detection of an interesting moment based on a user's degree of connection to the user in the video stream, location, attending of same event, likes, dislikes, profile settings, privacy settings, or any other information that may customize the detection of an interesting moment. For example, server 162 may analyze the first-degree connections of a user associated with client device 130 to determine that the threshold for detecting an interesting moment may be lower for a first-degree connection as opposed to a farther-removed connection. Moreover, server 162 may determine different interesting moments of a video stream for different users. For example, server 162 may identify one moment as an interesting moment for a first user, but not identify that same moment as an interesting moment for a second user.

While the disclosure discusses server 162 as receiving the one or more video streams and identifying an interesting moment in the video streams, the disclosure also contemplates the one or more client systems 130 receiving the one or more video streams and identifying an interesting moment in the video stream. Moreover, the one or more client systems 130 may identify an interesting moment in the video stream that client system 130 captured. Client system 130 may identify the interesting moment in its captured video stream and communicate it to one or more servers 162.

When an interesting moment is identified, server 162 may generate a marker for one or more of the video streams based on a time associated with the identified interesting event. The marker may be a flag associated with the video stream, a table identifying the time associated with the video stream, or any other type of indication for a time associated with the interesting moment. In certain embodiments, server 162 identifies a time period of the video stream containing an interesting moment, and generates a marker indicating the time period. In addition, server 162 may generate a marker that precedes or is subsequent to the identified interesting moment. For example, server 162 may place a marker five seconds before the identified interest moment occurs. The placement of the marker corresponding to the time associated with the identified interesting event may be preset or adaptive. Server 162 may also record and/or store the one or more video streams for a time period associated with the time related to the identified interesting moment. For example, server 162 may record a video stream ten seconds prior to the beginning time associated with the identified interesting moment and conclude recording the video stream only after ten seconds elapses after the end time associated with the identified interesting moment.

In particular embodiments, server 162 may associate information regarding the interesting moment with the information regarding the marker. For example, server 162 may associate information regarding the identified emotion with the information regarding the marker. Additional information, such as actions associated with the interesting moment, video stream associated with the identified interesting moment, or any information about the identified interesting moment may be associated with the marker.

Server 162 may then send information regarding the marker to the one or more client systems 130. Server 162 may communicate the information regarding the marker in near real-time, or server 162 may communicate the information regarding the marker after the video session is completed.

Server 162 may also send the one or more video streams associated with the video session to the one or more client systems 130. Client system 130 may pause, rewind, and fast forward through the one or more video streams associated with the video session. Client system 130 may communicate the pause, rewind, and/or fast forward of the one or more video streams to server 162, and server 162 may respond with a corresponding portion of the one or more video streams. Moreover, client system 130 may also store the received one or more video streams, such that client system 130 can process and display a paused video stream, rewind a video stream, or fast forward a video stream. Client system 130 may also provide an option to rewatch an identified interesting moment in the one or more video streams.

In certain embodiments, server 162 may provide an overlay to one or more video streams to one or more client devices, wherein the overlay comprises an audio and/or visual indication corresponding to the identified interesting event. In particular, server 162 may provide an audio or visual indication corresponding to an expression associated with the identified interesting moment. As an example, server 162 may provide a surprise emoji that corresponds to an identified expression of surprise. As another example, server 162 may provide an overlay of the one or more video streams that was identified as an interesting moment to one or more client devices. The visual and/or audio indication may comprise of any type of indicator identifying the interesting moment. In certain embodiments, client system 130 receives the one or more video streams and provides an audio and/or visual overlay corresponding to an identified interesting event.

In particular embodiments, a user of client system 130 may have the option to save the video session and share the video session with other users. Client system 130 may offer a user to replay an identified interesting moment in real-time while watching the video session. Moreover, client system 130 may create a replay of the video session by developing a video stream of the identified interesting moments. For instance, in a retroactive identification of an interesting moment, the method can identify portions of the video that contains interesting moments. With the portions identified, the video can be played back such that the interesting moments will be played during the video. In addition, the method may statistically analyze the interesting moments of a video. The statistical analysis may be particularly relevant to a video session wherein a multitude of watchers are watching a main speaker. Additionally, in a real-time identification of an interesting moment, the method can notify the viewing users of an interesting moment that occurred, and also an option to playback the interesting moment.

In an additional exemplary embodiment of operation, server 162 may maintain a persistent real-time group chatroom comprising zero or more participants. The persistent real-time group chatroom may, at any given time, have zero or more of the participants are active. The persistent real-time group chatroom participants may be participants that have authorization to communicate within the chatroom. Participants may synchronously communicate with other members of the chatroom. A chatroom may exist as a standalone application on client system 130, may be a native application on client system 130, or may exist as an embedded feature in a larger application (e.g., a chatroom inside Facebook). In a persistent real-time group chatroom, the chatroom may continue to exist even if zero participants are active in the group chatroom.

Server 162 may receive, from one or more client systems 130, one or more video streams associated with one or more users. Each client system 130 may respectively be associated with a user. Typically, a user operates client system 130. Client 130 may capture and communicate a video stream to server 162. In certain embodiments, client system 130 may encrypt and/or compress the one or more video streams before transmitting the one or more video streams to server 162.

Server 162 may provide a notification to one or more non-active participants. Non-active participants may be participants that are not active in the persistent real-time group chatroom. For example, non-active participants may be participants that do not have the group chatroom window active and/or open, participants that have not interacted in the group chatroom for a period of time, or any other type of participant that is not active with the persistent real-time group chatroom.

Server 162 may provide notifications in a myriad of ways. For example, server 162 may communicate an e-mail to an e-mail address associated with the non-active participant, server 162 may provide a notification through the group chatroom to the non-active participant, or server 162 may provide an indication on the one or more client systems 130 of the non-active participants. In certain embodiments, client system 130 may provide a pop-up notification on client system 130's user interface.

In certain embodiments, server 162 records the one or more video streams associated with one or more users. A non-active participant may view the one or more video streams associated with one or more users at a later time. Moreover, a non-active participant may view portions of the one or more video streams, forward through portions of the one or more video streams, or rewind portions of one or more video streams. In an exemplary embodiment, server 162 identifies interesting moments in the one or more video streams and generates a marker based on a time associated with the identified interesting moments. A non-active participant may view portions of the one or more video streams associated with the time indicated in the marker identifying interesting moments in the one or more video streams. Server 162 may also create a review video session, wherein server 162 generates a video session based on the markers of the identified interesting moments in the one or more video streams and the associated video streams during the time indicated by the marker. In certain embodiments, server 162 may create a review video session by recording a portion of the video stream a set or dynamic time period before the interesting moment marker and continue recording for a set or dynamic time period after the interesting moment marker. Moreover, server 162 may allow a user to jump to one or more interesting moments in a video stream.

Moreover, server 162 may receive, from one or more client systems 130, an action. An action may include a comment in the persistent real-time group chatroom, a like on the chatroom, or any other types of action that is associated with the one or more video streams. Server 162 may associate the action with a time and/or one or more video streams. Server 162 may communicate the action alongside the recorded one or more video streams to the one or more non-active participants. In particular embodiments, server 162 may communicate one or more video streams to the non-active participant, and also, simultaneously, communicate the action to the non-active participant during playback. Client system 130 may play the one or more video streams such that the action corresponding to one or more video streams replicates the real-time display of the action to the one or more video streams.

Server 162 may communicate the one or more video streams associated with the video session to client systems 130. Participants of the group chatroom may also pause, rewind, and fast forward through the one or more video sessions. Client system 130 may communicate the pause, rewind, and/or fast forward of the one or more video sessions to server 162, and server 162 may respond with a corresponding portion of the one or more video sessions. Moreover, client system 130 may also store the received one or more video streams, such that client system 130 can process a paused, rewind, or fast forward of one or more video streams. Client system 130 may also provide an option to rewatch an identified interesting moment in the one or more video streams.

Server 162 may also generate a link, wherein the unique link provides access to the persistent real-time group chatroom. A user of a client system 130 may use the unique link to access the persistent real-time group chatroom. The link may be a uniform resource location (“URL”), a link to a web address, a link to an application one the one or more client systems 130, or any other type of link that allows the one or more client systems 130 access to the real-time group chatroom. A user of client system 130 may provide the link to one or more users of additional client systems 130 to invite those one or more users to participate in the group chatroom.

In certain embodiments, a group chatroom comprises one or more administrators. Administrators may have the ability to accept or deny new participants to the group chatroom. Once an administrator accepts a new participant, the new participant may then interact with the other participants in the group chatroom. Moreover, server 162 may notify participants of the addition of a new participant in the group chatroom.

FIG. 2 illustrates an example method 200 for identifying and sending interesting events of one or more video streams in a video session. The method may begin at step 210, where server 162 may receive one or more video streams from one or more client systems 130. Client system 130 may capture a video stream by using a video camera, microphone, speaker, or any other mechanism to record video and/or audio. In certain embodiments, a video stream may comprise a video component, an audio component, or both a video and audio component. Client system 130 may transmit a video stream to server 162. In certain embodiments, multiple client systems 130 may each respectively transmit a video stream to server 162. Moreover, the video streams may be associated with a video session. A video session may comprise video streams from one or more video streams associated with one or more users wherein the one or more users are communicating with one another.

At step 220, server 162 may analyze the one or more received video streams to identify an interesting event. An interesting event may be any type of noteworthy event that occurs in a video stream. Server 162 may analyze the one or more received video streams proactively as client system 130 communicates a video stream to server 162 and/or server 162 may analyze the video streams retroactively. In certain embodiments, server 162 may associate one or more actions associated with a video stream as an interesting event. Server 162 may have a preset threshold for when to tag a video as interesting (e.g., a certain number of comments associated with the video stream) or the threshold may be adaptive. Server 162 may also detect a change in audio content and determine that as an interesting moment. Server 162, in addition, may analyze the audio spectrum of the audio stream to determine if a change in the audio is significant to warrant labeling as an interesting moment. In certain embodiments, server 162 detects a change in an attribute of the video stream and/or audio stream, and records that change as an interesting moment. Server 162 may also use facial recognition computer software to identify an emotion associated with a user of client system 130. In certain embodiments, server 162 may identify an interesting moment based on the emotion associated with the user of client system 130. Server 162 may also apply analysis on the environment captured in a video session of client system 130 by detecting a change in the environment, detecting an unusual pattern in the environment, or performing any other type of analysis such that server 162 can detect an interesting moment in the received one or more video stream. In particular embodiments, server 162 may customize the detection of an interesting moment based on information related to the user profile associated with client device 130. Server 162 may customize the detection of an interesting moment based on a user's degree of connection to the user in the video stream, location, attending of same event, likes, dislikes, profile settings, privacy settings, or any other information that may customize the detection of an interesting moment. Moreover, server 162 may determine different interesting moments of a video stream for different users.

At step 230, server 162 determines if the analysis of the one or more video streams identified an interesting event. If server 162 did not identify an interesting event, the method ends. However, if server 162 identifies an interesting event, the method proceeds to step 240.

At step 240, server 162 generates a marker for one or more of the video streams based on a time associated with the identified interesting event. The marker may be a flag associated with the video stream, a table identifying the time associated with the video stream, or any other type of indication for a time associated with the interesting moment. In certain embodiments, server 162 identifies a time period of the video stream containing an interesting moment, and generates a marker indicating the time period. In addition, server 162 may generate a marker that precedes or is subsequent to the identified interesting moment. Server 162 may also record and/or store the one or more video streams for a time period associated with the time related to the identified interesting moment.

In particular embodiments, server 162 may associate information regarding the interesting moment with the information regarding the marker. Additional information, such as actions associated with the interesting moment, video stream associated with the identified interesting moment, or any information about the identified interesting moment, may be associated with the marker.

At step 250, server 162 sends information regarding the marker to the one or more client systems 130. Server 162 may communicate the information regarding the marker in near real-time, or server 162 may communicate the information regarding the marker after the video session is completed. Server 162 may also send the one or more video streams associated with the video session to the one or more client systems 130.

Particular embodiments may repeat one or more steps of the method of FIG. 2, where appropriate. Although this disclosure describes and illustrates particular steps of the method of FIG. 2 as occurring in a particular order, this disclosure contemplates any suitable steps of the method of FIG. 2 occurring in any suitable order. Moreover, although this disclosure describes and illustrates an example method for identifying and sending interesting events of one or more video streams in a video session including the particular steps of the method of FIG. 2, this disclosure contemplates any suitable method for identifying and sending interesting events of one or more video streams in a video session including any suitable steps, which may include all, some, or none of the steps of the method of FIG. 2, where appropriate.

FIG. 3 illustrates an example method 300 for providing a persistent real-time group chatroom that notifies non-active participants of activity in the group chatroom. The method may begin at step 310, where server 162 maintains a persistent group chatroom comprising zero or more participants. The persistent real-time group chatroom may, at any given time, have zero or more of the participants are active. In a persistent real-time group chatroom, the chatroom may continue to exist even if zero participants are active in the group chatroom.

At step 320, server 162 may receive, from one or more client systems 130, one or more video streams associated with one or more users. Each client system 130 may respectively be associated with a user. Client 130 may capture and communicate a video stream to server 162. In certain embodiments, client system 130 may encrypt and/or compress the one or more video streams before transmitting the one or more video streams to server 162. Moreover, server 162 may receive, from one or more client systems 130, an action. An action may include a comment in the persistent real-time group chatroom, a like on the chatroom, or any other types of action that is associated with the one or more video streams.

At step 330, server 162 determines if one or more non-active participants are associated with the group chatroom. Non-active participants may be participants that are not active in the persistent real-time group chatroom. If there are no non-active participants in the persistent real-time group chatroom, the method ends. However, if there are non-active participants in the persistent real-time group chatroom, the method proceeds to step 340.

At step 340, server 162 provides a notification to the one or more non-active participants. Server 162 may communicate an e-mail to an e-mail address associated with the non-active participant, server 162 may provide a notification through the group chatroom to the non-active participant, or server 162 may provide an indication on the one or more client systems 130 of the non-active participants.

In certain embodiments, server 162 records the one or more video streams associated with one or more users. A non-active participant may view the one or more video streams associated with one or more users at a later time. In an exemplary embodiment, server 162 identifies interesting moments in the one or more video streams and generates a marker based on a time associated with the identified interesting moments. A non-active participant may view portions of the one or more video streams associated with the time indicated by the marker identifying interesting moments in the one or more video streams. In addition, server 162 may associate a received action with a time and/or one or more video streams. Server 162 may communicate the action alongside the recorded one or more video streams to the one or more non-active participants.

Server 162 may communicate the one or more video streams associated with the video session to client systems 130. Participants of the group chatroom may also pause, rewind, and fast forward through the one or more video sessions. Client system 130 may communicate the pause, rewind, and/or fast forward of the one or more video sessions to server 162, and server 162 may respond with a corresponding portion of the one or more video sessions.

Server 162 may also generate a link, wherein the unique link provides access to the persistent real-time group chatroom. A user of a client system 130 may use the unique link to access the persistent real-time group chatroom. The link may be a URL, a link to a web address, a link to an application one the one or more client systems 130, or any other type of link that allows the one or more client systems 130 access to the real-time group chatroom.

Particular embodiments may repeat one or more steps of the method of FIG. 3, where appropriate.
